rollup-plugin-unbundle

Rollup plugin to externalize dependencies that should not be bundled (e.g., dependencies, peerDependencies, Node.js built-ins). v3.2.0 adds Rollup v4 support. Maintained actively, with a focus on correct externalization and side-effect detection. Unlike manual external configuration, it integrates with @rollup/plugin-node-resolve and respects the package.json sideEffects field. Requires Node >=16.15 and Rollup 2.79.1 - 5.0. Ships TypeScript definitions.
